gma: Fix loop logic in Scan_Ports()

When deciding if a pipe has been configured, we only checked if reading
the EDID succeeded not if it contained usable data.

TEST=Booted kontron/ktqm77 with a DVI-I to VGA cable and the display
     came up (it didn't before because of a gap in the pipe config, i.e.
     the second pipe was disabled so coreboot didn't bother to look at
     the third).
